Pedicle screw-only constructs with lumbar or pelvic fixation for spinal stabilization in patients with Duchenne muscular dystrophy.
Retrospective case study. ⋯ Pedicle screw-only constructs provide good stability allowing better correction and maintenance of coronal and lumbar deformities, obtaining good sitting balance, and mobilizing patients early after surgery. Longer follow-up is required to adequately comment on the need for pelvic stabilization.

Randomized Controlled TrialThe use of screw at the fracture level in the treatment of thoracolumbar burst fractures.
In this prospective randomized study, the results of treating unstable thoracolumbar burst fractures by pedicle instrumentation with and without fracture level screw combination were given. ⋯ Reinforcement with fracture level screw combination can help to provide better kyphosis correction and offers immediate spinal stability in patients with thoracolumbar burst fracture.

Case ReportsCervical kyphotic deformity correction using 360-degree reconstruction.
The authors report on their experience with cervical sagittal deformity correction using 360-degree reconstruction. ⋯ The correction of cervical kyphotic sagittal plane deformity can be accomplished safely and effectively using a 360-degree approach. The incidence of major complications in this study was low. All patients could be corrected to a neutral or lordotic alignment. No loss of deformity correction was seen in any patient, and a 97.5% fusion rate was obtained.

Anterior transvertebral herniotomy for cervical disc herniation: a long-term follow-up study.
Retrospective study. ⋯ In conclusion, ATH provided a good clinical outcome that was maintained for a long time. Although intervertebral motion at the operated level decreased to some extent, degenerative changes at the adjacent levels were not enhanced.

Cervical spine imaging using mini--C-arm fluoroscopy: patient and surgeon exposure to direct and scatter radiation.
Direct and scatter radiation was measured during cadaveric cervical spine imaging with a mini-C-arm fluoroscope. ⋯ Although using a mini-C-arm unit may reduce exposure levels, substantial exposure to both patient and staff is still achievable. Use of a mini-C-arm for cervical spine imaging reduces exposure to the surgeon more effectively than to the patient. To lower the risk of radiation exposure in the cadaver laboratory, a mini-C-arm should be used in each instance that offers appropriate visualization. In the operating room, all appropriate radiation dose-reducing measures should be strictly enforced by supervising physicians to minimize risk to patients, medical staff, and themselves.
